Is there any guideline that tells when should we use pointer type and regular type in a struct(or class) definition?
For example:
For example:
1 2 3 4 5 6 7 8 9 10 11 | struct bar { int ID; int Handle; ... }; struct foo { bar *Bar; // <- Here how do we decide whether to use pointer type or just regular type i.e bar Bar; }; |

Reason: Initial post
If you need to store data itself or a copy, then you put a value type. If you need to reference the data that is stored in some other place - you use pointer. That's the whole point of pointers - to point to data in some other place.

Second link has bad information and very incorrect code examples - it is doing totally different things than claimed.
